Owner's Operation and Maintenance Manual

A-- 20
ENGINE BREAK-IN
With a basic understanding of how the snowmobile works, and with close attention
paid to maintenance tips, you will be ready to ride. Keep in mind these recommen-
dations as well as those covered throughout this manual.
CAUTION
D Never mix brands of oil. Serious chemical reactions can cause oil passage
blockage, resulting in severe engine damage and voiding of engine war-
ranty. The only oil recommended for this system is Polaris Premium 4 All
Season Synthetic oil. This oil has been specially formulated for all temper-
atures and has extreme cold flow characteristics.
D Do not operate at prolonged full throttle for the first threehours of operation.
Vary the throttle openings and machine speeds. This will reduce friction
on all close fitting machined parts and allow them to break in slowly without
damage.
D Avoid operating on ice or hard-packed surfaces, roads, etc. The absence
of lubrication and cooling by snow will lead to overheating of the slide rail
and track resulting in premature wear and failure. Reduce speeds and fre-
quently drive into fresh snow to allow adequate cooling and lubrication of
the slide rail and track surfaces.
D Drive with extra caution during the break-inperiod. Perform regularchecks
on fluid levels, lines, and all important areas of the machine.
